Former president Trump encourages foul-mouthed chants at enormous New Jersey re-election rally where he branded Biden administration 's**t' and called NY AG Alvin Bragg 'Fat Alvin'

Donald Trump unleashed a torrent of foul-mouthed chants and insults during a massive re-election rally in New Jersey on Saturday attended by close to 100,000.

Trump, who for the last three weeks has been stuck in a Manhattan criminal court appeared ready to unload and took aim at President Biden, Manhattan District Attorney Alvin Bragg and the judge in his hush money trial.

At one stage he persuaded the gathered crowd to take part in a low-brow call and response act that would see them call the Biden Administration 'S**t!' 

'Everything they touch, turns to what?', Trump asked.

'S**t!' the crowd shouted enthusiastically in response.

'You can't use the word s**t,' Trump said laughing.

Trump blasted then Democratic president 'a total moron.' 'He's a fool. He's not a smart man,' Trump said of Biden. 'I talk about him differently now because now the gloves are off.'

The rally took place in the Democratic stronghold of New Jersey, but tens of thousands appeared to turn out in the beachside town of Wildwood, a conservative enclave in an otherwise blue state, 150 miles south of New York City.

Trump called Bragg 'fat Alvin' before describing the New York judge who is presiding over his trial, Juan Merchan, as 'highly conflicted.' 

He brought up allegations that both Bragg and Merchan are 'doing the bidding' of President Biden, despite having no evidence to support that claim.

The hush money case was filed by local prosecutors in Manhattan who do not work for the Justice Department or any White House office. The Justice Department has said the White House has had no involvement in the two criminal cases against Trump brought by special counsel Jack Smith.

The judge in the hush money case already has already fined Trump $9,000 for violating his gag order and warned that jail could follow if he doesn't comply. 

The order does not include references to Judge Merchan or DA Bragg, both of whom Trump said are 'doing the bidding for crooked Joe Biden.' 

'Fat Alvin, corrupt guy,' said Trump bluntly. 

Trump's return to the campaign trial comes at the end of another week where he has been holed up in a New York criminal courtroom.

Trump is currently facing 88 criminal charges in four separate indictments on which he had plenty to say during Saturday's rally noting how he was indicted on 'bulls***.''

'I've been indicted more than the great Alphonse Capone. Scarface. Al Capone was so mean that if you went to dinner with him and he didn't like you, you'd be dead the next morning. And I got indicted more than him! Bulls***!' Trump yelled.

It led to the crowd chanting back the word 'bulls***' back to him as he stood at the podium. 

Trump could be seen chuckling to himself as supporters got behind his chanting while also cursing.

He then went on to attack the former Republican governor of New Jersey, Chris Christie.

'So I was in New Hampshire and he was fighting, fighting, like totally unhinged,' Trupm said of Christie, adding that he was as 'major case of Trump derangement syndrome.'

'And somebody from the front row said, "Sir, he's a fat pig." The person was a nice person. I said, "You cannot call Chris Christie a fat pig ... please sir, if you call him a fat pig once more I'm going have to have you leave the arena,"' Trump said he said.

'And the guy didn't know what was happening,' Trump continued. 'I said, don't worry about it, I'm only kidding. But I said you cannot call him a fat pig because you're not allowed to use the fat word.'

'You know you can use almost any word but you can't use the fat word - it's career ending, if you call somebody fat, it's career ending,' the ex-president added.

'You cannot call him a fat pig,' Trump instructed the crowd with a wink.

Trump then went back to his campaign rally's greatest hits as he spoke about migrants coming to the U.S., describing their arrival as 'an invasion', vowing to 'stop the plunder, rape, slaughter and destruction of the American suburbs, cities and towns. 

'We're letting people come into our country that will only be trouble,' Trump warned.

Trump, who will face Biden in November's polls, is using increasingly violent rhetoric around the country's migrant crisis.

Just months ago, the Republican claimed that migrants were 'poisoning the blood' of the United States, sparking a fierce backlash.

Biden's campaign accused him of imitating the language of Hitler.

He went on to describe those who openly criticize him as 'the enemies from within are more dangerous to me than the enemies on the outside' the country.

The rally appeared to be something of a release for Trump who has been forced to keep quiet while sitting through his criminal trial each day, essentially preventing him from going on the campaign trail.

Although Trump addresses the media at the end of each day as he leaves the courthouse, few supporters are present to hear his ramblings.

But on Saturday evening he was back his element once again, riffing off the gathered masses.

Although New Jersey is a reliably Democratic state, parts of the Garden State have deep-red enclaves and the southern shoreline in particular draws tourists and summer homeowners from neighboring Pennsylvania, a key swing state. 

'Do I feel comfortable with you? I love you', he told the crowd.

Supporters were excited to see him, lining up from early in the day, hours before he was scheduled to take to the stage. 

Thousands of Trump loyalists donned 'Never Surrender' T-shirts and red 'Make America Great Again' hats as they crowded onto the sand between the boardwalk and carnival rides.

Some sat in chairs on the sands while others made an afternoon of it bringing beach blankets to sit on. 

'The everyday American people are 100% behind him,' said Doreen O´Neill, a 62-year-old nurse from Philadelphia.

'They have to cheat and smear him and humiliate him in that courtroom every single day,' O´Neill said. 'This country is going to go insane if they steal the election again.'

Lisa Fagan, spokesperson for the city of Wildwood said estimates of crowd were between 80,000 and 100,000 attendees. 

Trump was joined on stage by several high-level endorsers including North Dakota Governor Doug Burgum and NFL Hall of Fame linebacker Lawrence Taylor, who is still listed as a registered sex offender after pleading guilty in New York in 2011 to misdemeanor criminal charges of sexual misconduct and patronizing an underage prostitute.
